Item Direct torque controlled induction motor drive for electric vehicles application /(IEEE, 2023-06-01) Thangalakshmi, S.Manufacturers are now very interested in the motorization control of commercial Electric Vehicles (EVs). This paper describes an Induction Motor (IM) control methodology used in EV applications. Motor drive control is critical in EVs, and IM-based drives are better suited for EVs. For IM drives, there are essentially vector and scalar control techniques. Low performance is a disadvantage of the scalar control approach, but Direct Torque Control (DTC) is an excellent approach for IM speed control by effectively controlling the torque and flux. The alternating current (AC) is taken as a source and connected to a rectifier circuit. However, the functioning of the Voltage Source Inverter (VSI) with variable switching frequency might be determined by the availability of hysteresis controls for torque and flux. The DTC-controlled IM drive is developed in MATLAB/ Simulink tool and the performance of the motor is evaluated by the obtained results. The motor’s torque and speed response are examined.Item Designing and controlling the speed of single phase induction motor using raspberry pi System(Journal of Embedded Systems and Processing, 2017) Thangalakshmi, S.; Dinesh, M.The induction motors are widely used in industrial drives since of their low cost and flexibility. The control facet is very essential for any drive. This paper proposes an economical method of INDUCTION MOTOR speed control with efficient performance. The induction motor speed variation can be easily attained for a short range by stator voltage control. The terminal voltage across the stator winding of the motor can be varied to achieve the preferred speed control by controlling the firing angle of the semiconductor power devices (TRIAC in this paper). RASPBERRY PI 2(model B) plays an important in our project. Raspberry Pi is very small in size and it is a low cost device. Raspberry Pi has a Quadcorebroadcom BCM2836 900 MHz processor and 1GB RAM. It can perform all the work similar to a computer and can be referred as minicomputer. Python language must be used for this. It uses Raspbian operating system based on Debian distribution of LINUX.
